Bolt VS-570P overview

  • 1Description

Create light around your subject or augment existing light with the VS-570P Wireless TTL Flash from Bolt. Available here to be fully compatible with Pentax/Samsung's TTL (except for K-1 series), including use as a wireless master or slave TTL flash, the VS-570P allows photographers to work quickly and comfortably by knowing that settings can be easily determined with the camera's automatic metering system. This unit also has good power output with a guide number of 141' at ISO 100 and 50mm and can cover a range of focal lengths from 24-105mm using the zoom head, or as wide as 18mm with the pull-out diffusion panel. You can even control output manually with power settings from 1/1 to 1/64.

In addition to wireless TTL, the VS-570P can be set up as a manual master with an optical pulse that features a range of 33' or a simple optical slave. Multiple sync modes are available for complete control over your images, including high-speed sync and both 1st and 2nd curtain sync settings. The flash also has a recycle time of 0.5-9 seconds and can run on either 4 AA batteries or an external power pack, thanks to the inclusion of an HV power port. Additionally, for basic off-camera use it has a standard PC sync terminal.

    Bolt VS-570P reviews

    VS-570P Wireless TTL Flash for Pentax/Samsung Cameras is rated 2.3 out of 5 by 3.
    Rated 5 out of 5 by from A wonderful value in a Pentax-compatible flash I got this specifically for use on a Pentax K-3II. I especially wanted to use the high speed sync mode, for use with higher shutter speeds outdoors. I found the unit well constructed, with the settings very easy to change via the buttons and screen on the back. It starts in TTL mode, and it seems perfectly compatible with the Pentax in my initial tests. Focus aid worked too. Setting it in HSS mode, I was able to stop way down and use very high shutter speeds to use the flash on say brightly lit flowers with shaded spots. Worked great. Not the most powerful flash I've ever owned, and not as quick to fire in succession as many, but those cost WAY more. All in all I'm very pleased.

    Rated 1 out of 5 by from Build Quality and Poor Customer Service. I received my first unit to use HSS on my K-1, it worked great for about 5 min. Then it would charge the flash but would not fire.� I then returned it to BandH and received a second unit, it would not fire on pttl in Full Frame mode, even though the last unit did. I sent an Email to Bolt Tech Service, they said it was my camera and I should talk to Pentax, and now the second unit will not even turn on, and BandH says it is not eligible for a return. So frustrated with this process, Hopefully I can help someone else from making a mistake and purchasing this Flash.

    Rated 1 out of 5 by from Doesn't work with K-1ii I wrote a good review of this flash for the K-3ii. But I cannot get it to work in TTL or HSS mode on the Pentax K-1ii, so I cannot recommend it for that camera even at this price.
